The Barker (31342) is a relatively inexpensive portable waste tank that is a great fit for camping with a travel trailer due to its dual bracket system, portable seat, and built-in carry handle, making it an ideal option for small recreational vehicles.

With 60 inches of vertical clearance, the Barker can easily fit on the ceiling of a small trailer or in the middle of a camper. The lid of the tank can be used as a foot pump to make dumping waste easier and come with a valve that can be set to keep the tank topped up with water if you’re planning to empty it less frequently. Additionally, the included toilet seat cover can be removed to allow you to use the Barker as a shower or toilet if your RV is not ready to hook up to your sewer system.

We decided to choose the Camo Rhino 21 Gallon Portable Waste Holding Tank as our number one pick because it is a good quality product with a decent price. It comes with a special valve and spigot.

The spigot makes sure that there is no leak, therefore, there is no odors. It is also easy to empty. The spigot is made like a fountain so you have fewer chances of making a mess.

Thetford

Pros:

  • Automatic opening for hands-free handling
  • Adjustable tip can be closed to prevent a leak
  • Attractive design

Cons:

  • The automatic opening doesn’t work all the time
  • You may need to manually push the lid up after dumping

Here is the Thetford portable waste tank with an 18-gallon capacity. The tank is easy to install, and it’s made of durable material that won’t rust or crack. In addition, the tank is leak-proof thanks to its convenient tank design with an auto-open lid.

This model is equipped with an interior partial baffle that divides the tank into two compartments, one for collecting wastewater and the other where you pour clean water.

Lastly, it’s worth noting that one of the most important features of this tote tank is its automatic lid opening. To open the lid automatically, simply press on the lid, and the tank will automatically open up for you. However, the automatic opening doesn’t work all the time, so you may need to manually push the lid up after dumping.

One of the best portable waste trucks that I’ve personally tried is the Tote-N-Store 25609 Portable Waste Transport. It didn’t leak a drop of any mess, and you can safely store it without a problem.

The waste transport bags are sold separately. If you like to change them regularly, disposing of the waste is a simple task with these units.

The price is excellent as well.

This waste container has four swivel wheels and comes with four rubber feet that provide you with extra stability, even on uneven surfaces. These feet give you approximately 0.5” of clearance beneath the container, enough if you find yourself parking on an uneven surface.

Frequently Asked Questions (FAQ)

What is the best portable RV waste tank?

If you plan to park rather than boondock, then we would choose the Thetford 33570 Portable RV Tank Level Indicator for a few reasons. First it’s long-lasting, high-quality construction, but also the incredible amount of detail that went into building this portable RV toilet tank.

Everything from the extra hand grips and wide top opening to the indicator lid and the built in toilet paper holder feels sturdy and well-made. We also like how this tank is easy to use, simple to transport, and doesn’t take up much space. It even has a carrying handle and comes with both an RV-sized toilet seat and a secure lid that seals everything in.

How do you empty a portable RV waste tank?

Once you've decided on a good-sized portable waste tank for your RV, the next thing you need to do is empty it. Thankfully, this part is easy so long as you know what you're doing. Most waste tanks have valves that either slide or twist; you'll need something similar to a garden hose washer (often included with your tank) to push it up into the valve. Do this and close the valve off, and then simply unscrew the funnel from the tank and you're ready to empty.

Some tanks come with a small pump that should help get the waste out with very little effort. Some still require you to use a standard garden hose; in this case what you'll want to do is hook your hose to the sewer. Run the hose outside of your RV, and then use it to push the waste out into a sewage tank or a drain.

What is the best RV black tank treatment?

Charlie's bacteria and enzymes lubricate, digest and convert waste matter into odor neutralization, which is released into the water. Each dose is guaranteed to eliminate odors for up to six months. Just add 2 tablespoons per tank fill and dump when you're back home for a fresh start.

Charlie's Soap is one of the best-known tank treatment brands, and with good reason: It works great, and it's inexpensive.

The downside is that the included measuring spoon doesn't give you a lot of latitude to over- or underestimate your dosage, which makes it an iffy proposition for travelers who may not remember the last time they visited the dumping station.

How often should you dump your RV tanks?

For many, the smell of the waste tanks is the most loathed element of owning a recreational vehicle. The odor is caused by volatile organic compounds that decay and attract flies to the area. Maintaining a tank to prevent odors and bacteria buildup is important to avoiding contamination of your RV system.

To maintain the odor in wastewater tanks, it’s important to inspect it at least every few days to see how much has built up. If the tank smells, you should take it into a dumping station or empty it into an RV toilet immediately. Continue emptying the tank or taking it to the dump station until the odor has subsided.

Since the tanks are inside the RV, it’s harder for sunlight to reach into the tanks and break down the waste material. This makes it far more likely to build up and cause buildups or odors.

Conclusion

We know how difficult it can be to look for the best RV waste tank, as there are literally so many options out there. We listened to the concerns of RV owners around how complicated it can be to find the best RV waste tank for the price. Whether you're in search of a small RV toilet or a large RV vacuum toilet, we've narrowed down our top RV toilet list into 7, because we know how difficult it is to stand out from the crowd when it comes to selecting a great RV toilet.
